Abstract
The data presented here are related to the research paper entitled "Rare sulfated purine alkaloid glycosides from Bruchidius dorsalis pupal case" [1]. In this data article, we provide 1D and 2D nuclear magnetic resonance (NMR) spectroscopy and electrospray ionization mass spectrometry (ESIMS) data of three undescribed sulfated purine alkaloids, locustoside A disulfate, saikachinoside B disulfate, and saikachinoside A trisulfate isolated from the pupal case of the wild bruchid seed beetle Bruchidius dorsalis (Chrysomelidae, Bruchinae) infesting the seed of Gleditsia japonica Miquel (Fabaceae).
